"I had a problem room that had little insulation. Cold in the winter. Hot in the summer. No attic access. Energy services group was able to drill large holes in the ceiling & outside wall and spray in insulation. Then plug the holes and spackle. Replaced canister lights with led ones. They explained to my wife what they were going to do before it happened. Then said what they actually were able to accomplish. Great communication. Quick to schedule. Cleaned up after themselves. A quality company"

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

Drywall Insulation FAQs, answered by experts

Plaster provides a durable, soundproof, and moisture-resistant finish compared to drywall.

While certain types of textured walls can seem dated (looking at you, popcorn), textured walls are a common sight in both older and more modern homes. The main reason textured walls may be here to stay is that they are an excellent way to hide minor imperfections on a wall and give it a finished appearance. Some homeowners think a coat of paint on drywall is a bit industrial-looking. However, that look works perfectly in modern home design. 

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

Wet-sanding and dry-sanding each have pros and cons. Dry-sanding is less messy, so it’s a good option if you’re trying to minimize dust (for example, if you’re sanding an occupied home or working with particularly dry or dusty drywall mud). However, dry-sanding is quicker because you don’t have to keep rinsing a sponge or wait for it to dry before painting.

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.
